SASH-HOLDERi Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed October 8, 1906. Serial No. 337,880.

of which the following is a specification.

This invention relates to improvements in sash holders. In railroad cars the window sash is lowered by gravity and when in its raised position is held by a latch which may be released by the fingers. Very often the sash binds in the casing and'through carelessness or neglect is not pushed up until the latch is locked in its raised position. In many instances the sash is held in its raised position by friction until the vibration and jarring of the car gradually cause the sash to become released and fall. Many times it happens that a passenger ignorant of the fact that the window is not latched, and not realizing the danger places his hand or arm on the window sill in such a position that when the sash falls it strikes his hand or arm, thereby injuring the same. By reason of these accidents railroad companies are often compelled to pay heavy damages.

The object of this invention is to provide a sash holder which may be secured to the side of the window casing near the bottom, so constructed and arranged as to prevent the occurrence of the above described accidents, and it is further the object of this invention to provide a sash holder of the character described which is so constructed that it cannot be tampered with and thus rendered inoperative.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a vertical sectional elevation of a car window with my improved sash holder thereon, the sash being shown in its closed position. Fig. 2 is a sectional elevation of the same showing .the sash partly raised and resting upon the The plate 5 is provided with a boss 8 extending into a hole bored in the window casing 7. An arm 9 is rotatably mounted on a pivot 10, said pivot being rigidly secured to the plate 5. A pin or projection 11 fast to the arm 9 extends into a slot 12 formed in the plate 5 concentric with the pivot 10, whereby the angle through which said arm may be rocked in opposite directions is limited. The plate 5 is preferably provided with a raised portion 13 to reduce the frictional area between the arm 9 and said plate. Said plate is also provided with a flange or rib 14 against which the arm 9 bears when in the position shown in Fig. 2, said flange being adapted to receive art of the shock when the window sash 15 alls on the arm 9.

The arm 9 is so formed, the pivot 10 is so arranged with relation to the sash 15 and the arrangement of the projection 1 1 and the slot 12, are such that the center of gravity of the arm 9 at all times lies at the right of-the line 33, Fig. 1. In other words, the whole is so constructed and arranged that by reason of gravity the arm 9 at all times tends to swing toward the right. Thus it will be seen that when the sash is closed as shown in Fig. 1, the arm 9 bears against said sash and when the said sash is raised the arm 9 swings into the path of movement of said sash and said arm occupies the position shown in Fig. 2.

As hereinbefore stated it is customary to have a latch to retain the sash 15 in its raised position. If said latch should fail to hold the sash 15 in its raised position and said sash should drop it will strike the arm 9 as is illustrated in Fig. 2 and will thus be prevented from falling on the hand or arm which may be lying across the window sill 16.

When it becomes necessary to entirely close the sash 15, said sash may be slightly lifted and the arm 9 may then be withdrawn from the path of movement of said sash and said sash may then be allowed to close as shown in Fig. 1. In Fig. 4 I have illustrated a modified form of my invention in which a flange 17 is substituted for the pin 1 1 and the slot 12 of the form hereinbefore described, the device being in other respects identical with the form hereinbefore described.

It will be noted that there is but one moving part in the device of my invention, namely, the pivoted arm and by reason of this it is impossible to render the device inoperative by tampering with it. It will be seen that by reason of the features of construction hereinbefore described, if one should move the arm 9 from the position shown in Fig. 2 and then should release it, said arm will by gravity instantly return to the position shown in Fig. 2.

Having thus described my invention what I claim and desire by Letters Patent to secure is:

1. A sash holder comprising a plate adapted to be fastened to a window casing, a pivot rigidly fastened to said plate and extending therefrom parallel to the face of the sash, an arm mounted upon said pivot and adapted to rock thereon, and means rigidly fastened to one of said parts adapted to engage the other of said parts at the opposite ends, respectively, of the rocking movement of said arm, whereby the angle through which said arm may be rocked in opposite directions is limited.

2. A sash holder comprising a plate adapted to be fastened to a window casing, a pivot rigidly fastened to said plate and extending therefrom parallel to the face of the sash, an arm mounted upon said pivot and adapted to rock thereon, and a pin fast to said arm and projecting into a slot provided in said plate concentric with-said pivot, whereby the angle through which said arm may be rocked in opposite directions is limited.

3. A sash holder comprising a plate adapted to be fastened to a window casing, a pivot rigidlyfastened to said plate, an arm mounted upon said pivot and adapted to rock thereon, a pin fast to said arm and projecting into a slot provided in said late, and a projection on said plate adapte to engage said arm at one end of the angular movement thereof,

whereby the angle through which said arm may be rocked in opposite directions is limited.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- HGSSGS.
